Abstract

This utility model belongs to the field of emergency shut-off valve testing technology, specifically a functional testing device for an emergency shut-off valve of a refrigerated liquefied gas tanker truck. It includes a test bench with an air intake mechanism and a detection mechanism mounted on it. The air intake mechanism and the detection mechanism are respectively installed at opposite ends of the test bench, with a valve body positioned between them. The detection mechanism includes a first conical tube, with a detection tube connected to its end. A pressure sensor is installed inside the detection tube, and a moving component is connected to the detection tube to move the first conical tube. This utility model uses the moving component to move the detection mechanism, fixing the valve body between the air intake mechanism and the detection mechanism. The valve body is clamped and fixed by the first conical tube in the detection mechanism and the second conical tube in the air intake mechanism. Therefore, the first and second conical tubes can quickly fix the valve body and connect it to the equipment, thus improving testing efficiency.
